We have a custom hardware based on STM32MP1 along with Cypress43455 (IC: LBEE5HY1MW-230) and other peripherals. For our use case, we are using Yocto Linux and OpenSTLinux (arm-openstlinux_weston-linux-gnueabi-gcc), Kernel version 4.19.9. Kernel modules for the Cypress43455 have been backported from Linux version v5.4.18-2020_0402 (Firmware version: 7.45.206).

For Wi-Fi, we load the following Cypress Wi-Fi modules to the kernel:
compat.ko
cfg80211.ko
brcmutil.ko
brcmfmac.ko

Our board utilizes wlan0 interface for connectivity with the internet and also has a virtual network interface wlan1 (created using the "iw dev wlan0 interface add wlan1 type __ap" command with "ifconfig wlan1 $GATEWAY up") to provide host Wi-Fi.

On wlan0 (as STA), we use wpa_supplicant, initiated by "/usr/sbin/wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf" along with "dhclient wlan0" for DHCP client initialization.

On wlan1 (as AP), we utilize hostapd, started with "hostapd /etc/hostapd.conf -B" along with "udhcpd /etc/udhcpd.conf".

The issue arises when the wlan0 interface experiences disruption/disconnection, causing wlan1 interface to be affected. Devices attempting to connect to the wlan1 interface fail to establish a connection, even after wlan1 has been brought up for some time. These devices' wpa_state remains as "SCANNING".

What could be the cause of this issue? How to overcome this? Appreciate any responses in advance.

Hello , I'm trying to integrate a module that integrate the chip BCM4373, under yocto. This chip is connected under SDIO on a x86 intel atom board. I try to integrate the linux backport but isn't working , is there a way to integrate the module with the mainline kernel and brcmfmac driver ? Which kernel configs i should add ? For now i include this ones : CONFIG_CFG80211=y CONFIG_WLAN=y CONFIG_NETDEVICES=y CONFIG_WLAN_VENDOR_BROADCOM=y CONFIG_BRCMUTIL=y CONFIG_BRCMFMAC=m CONFIG_BRCMFMAC_SDIO=m CONFIG_DRIVER_HOSTAP=y CONFIG_BRCMSMAC=n CONFIG_BRCMFMAC_USB=y CONFIG_SDIO_UART=y The firmware is corectly load in rootfs but driver isn't working for now. Thanks Show Less

 Hi,

I'm just wondering if the CYW43012 low power wifi can pass through from low power internal IP stack running on MCU fmac driver running on linux, i.e. we have the device it low power mode connected to wifi access point and remote service, on wake we want to start linux and hand over wifi connection state to linux driver.

Can this chip support a solution like this?

Hi, 

I understand following issue.

https://community.infineon.com/t5/AIROC-Wi-Fi-MCUs/The-failure-of-sample-code-STM32-Connectivity-Pack-by-Murata-Type1LV/td-p/680618?emcs_t=S2h8ZW1haWx8c29sdXRpb25fdG9fcXVlc3Rpb258TFM4UE5VREYxTE5MOVF8NjgyMzc0fEFDQ0VQVEVEX1NPTFVUSU9OU3xoSw#M957

But I found the another issue of sample code (Wi-Fi onboarding with Bluetooth® LE) STM32 Connectivity Pack by Murata Type1LV.

When this sample code was executed by stand alone, BLE was not connected between iPhone and Type1LV.

Please let me know the cause of this issue.

1. iPhone application could not find Type1LV.

 

 

2. The following information (send failure) was insicated by serial communication application.

 

The emvironment information is following.
- Wifi module: Murata Type1LV (CYW43012)
- Evaluation board: STM32H747 DISCO Kit, muRata uSD-M2 Adapter Kit (rev B1), Embedded Artists 1LV M.2 Module
- Sample code: wifi_scan in STM32 expansion Pack 1.5.1

 

Best Regards,

Tsutsumi
